I visited a friend last week. She lives in Chiba, less than an hour away from Tokyo.
There are lots of things to see in Chiba. Disneyland and Disney Sea are there. (The name Tokyo Disneyland is wrong technically.)
There's Chiba Tower, Lighthouse and the Tokyo Bay Aqua Line.
If we wanted to see more shrines and temples, Nihon-ji Hokekyo-ji, Tanjo-ji, Manman-ji, Awa Shrine and Chiba-dera are just all around Chiba.
Had we felt really genki (genki means active), we could have hiked Mt. Tomi, Mt. Atago or Mt. Nokogiri.
If we wanted a leisurely cultural day, we could have visited Kawamura Museum of Art, Nambo Paradise Botanical Garden, Museum of Science and Industry or Suigo Sawara Aquatic Botanical Garden.
There are really a lot of possible places to visit in Chiba. But, my friend and I didn't go to any of those places. Instead, we went to a very foreign place- COSTCO!
